Descriptive Statistics These simply describe the attributes of a single variable. You cannot test here (you need two variables) Why do them?
Categories of Descriptive Statistics Measures of Central Tendency The most common, the middle, the average Mean, Median and Mode Measures of Dispersion How wide is our range of data, how close to the middle are the values distributed Range, Variance, Standard Deviation

Finding the Median location of median case (1747+1)/2 = 874 Where Does that case fall? – Case 1 through 534 = has value of 0 – Case 535 through 1747 = has value of 1 Case 874 is more than 535 and less than 1747 THE MEDIAN IS 1, the category is voted You can also look here for where 50% falls
